• Use of an ATX 12 V Specification 2.0-compliant power supply unit (PSU)
that provides a minimum power of 350 W is recommended for a fully-
configured system.
• Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the
system will not boot up.
• Use of a power supply unit (PSU) with a higher power output is
recommended when configuring a system with more power-consuming
devices. The system may become unstable or may not boot up if the power
is inadequate.
• Make sure that your PSU can provide at least the minimum power required
by your system.
